What the ZephyrAxis Measures and How It Is Built
Barometer Pressure Trend
The solid-state barometer logs pressure change over time and shows whether pressure is rising or falling. You read the trend on the screen next to the wind and temperature values.
USB-C Rechargeable Battery
The meter runs on a rechargeable battery. You charge it through the USB-C port with the included cable, from any USB-C power source, and the unit then works without cords in the field.

Sealed Housing
The housing is sealed and the controls are moisture-resistant, so the meter can be carried outdoors. Wipe it down after use and store it dry with the strap attached.
External Temperature Probe
The thermistor probe sits out in the airflow instead of inside the device body. That keeps the temperature sensor away from the heat of the housing and your hand.

ZephyrAxis is a wind speed meter that uses an impeller to read airflow where the user stands. The backlit screen shows wind speed, gusts and averages. As a hand held wind meter, it comes with a hand strap for field grip.
An external thermistor probe measures air temperature away from the warm device body. A solid-state barometer logs pressure change over time to show rising or falling trends. The portable wind speed meter also reports CFM air volume, so it doubles as an air speed meter for HVAC and ventilation work.
Power comes from a rechargeable USB-C battery with an automatic shut-off when idle. The wind speed meter has a sealed housing, and the impeller can be replaced by the user. As a digital wind speed meter, it ships with:
- Hand strap
- USB-C charging cable
- Precision screwdriver
- Full user manual
